[flakey] Skip ray_syncer_test for ubsan. (#25477)

From the message:
```
[       OK ] SyncerTest.TestMToN (13132 ms)
[----------] 5 tests from SyncerTest (43175 ms total)

[----------] Global test environment tear-down
[==========] 8 tests from 2 test suites ran. (43176 ms total)

external/com_github_grpc_grpc/src/core/lib/iomgr/ev_posix.cc:314:19: runtime error: member access within null pointer of type 'const struct grpc_event_engine_vtable'
```

This can only be reproduced by running with Bazel test so far. With gdb, it won't be reproduced. It seems like some issue with the grpc maybe the reactor API. 
Given that the ASAN test, which is supposed to catch the issue, runs well, and a considerable time has been spent investigating this one but no progress, skip this test for now.
